GS21HTZCB0 Frigidaire Refrigerator - Instructions

First I removed the plastic grill (pulled out, no screws) from bottom of refrigerator, then I removed electrical plug & two screws from old timer (timer located on the front inside left lower side of refrigerator). Installed in reverse order.

Removed four screws for cover on refrigerator temperature controls, unpluged old timer and pluged in new timer. Replaced cover and screws.

Popped the old one out and pressed the new one in. Very easy. Pressed new one in my hands. Fits in a channel. Very easy

Checked for continuity in heater, defrost thermostat and defrost timer. Heater good; not sure about thermostat or timer. Replaced thermostat - no change. Replaced timer - rotating and heater working.

I watched You Tube on how to repair it the instructions that came were shit. I'm a stickler for wire colors being correct, could find that information in the instructions. Everything is on you tube I love you tube. The fix is is easy peasy. I'm not stupid eather there is nothing on that frig I could not repair if I can get parts even the compressor I can braze to. I know how it all works I never call repair people I will throw it all in the garbage if I can't get parts. That goes for TV's cars you name it. I have tools for all things.

I watched the video on how to change the defrost thermostat. I removed the back cover inside the freezer then I pulled off the old defrost thermostat and then using a pair of wire cutters I cut it off and then bared a little of both of the wires and then slid the heat sherink and wire connectors on the existing wires and then slid the other ends of the wires into the wire connectors then crimped the ends of the connectors and then tried using heat on the heat shrinks but still used rubber electric tape over it. I clipped the new thermostat were the old one was and then reattached the freezer wall cover and plugged the refrigerator back in. 24 hours later I checked the temperature in the refrigerator and freezer and both are running a lot colder.

I removed the housing at the top of the refrigerator compartment that contained the reefer light and temperature adjustment knob. This required a small nut-driver. Inside, I found the old defrost control, unplugged it, unscrewed it with a Phillips screwdriver, and replaced it with the replacement part. Then I replaced the housing to its original position.

The repair was not difficult because you just remove the old part and plug it in and connect two wires. But I wish there was a way to test if the compressor is working before I purchased the parts. The compressor would not start so I was not able to repair the refrigerator.

Removed the screws on the piece holding the switch which is at the front of the ceiling of the refrigerator box. Removed the old switch and replaced it. Very simple repair.

I called the repairman who diagnosed the problem as a thermostat then had to order a thermostat took about 2 weeks to get back and install (cost little over $100). did good for about two weeks and same problem reoccured. I decided it was defrost timer and ordered from this site for $19.95 including shipping. I got on ( you tube ) and got instructions(recommend you tube) for DIY install about 15 to 20 minutes. Has been running great for about 3 weeks. ( YOU TUBE IS GREAT FOR A DIY REPAIR ON ABOUT ANYTHING)

The bulb has a plastic clear cover. That cover can just be carefully removed using a screwdriver. It's held in by a metal bracket. After you remove the cover. You'll just need to replace the bulb and then re-install the cover and bracket.

I started look inside ,disconnected power, and open all possible compartments to see any burned part. Fortunately I fined a small part look like melted and then i went online and make my research .Then i ordered that part and change it.

I removed the plastic shroud on the ceiling of the refigerator, unscrewed and unplugged the old defrost timer, and replaced it with the new one. I reinstalled the shroud with the new timer installed.

I can't believe I put if off so long... so easy to do and PartSelect was very fast, efficient, and the cheapest vendor for my part.

purchased a new freezer gasket. It is still iceing in the freezer but now all over the top part and down the back. The new gasket does not secure tight enough around the entire freezer door when it is closed. It is secured properly to the door but does not "grab" tight enough when the freezer door is closed.
